Introduction to SDL with Emscripten

First, you should have the Emscripten SDK installed from:

https://emscripten.org/docs/getting_started/downloads.html

We'll start by creating a simple project to build and run hello.c

Building SDL

Once you have a command line interface with the Emscripten SDK set up and you've changed directory to the SDL directory, you can build SDL like this:

mkdir hello
cd hello
emcmake cmake ..
emmake make

Building your app

In this case we'll just run a simple command to compile our source with the SDL library we just built:

emcc -o index.html ../docs/hello.c -I../include -L. -lSDL3

Running your app

You can now run your app by pointing a webserver at your build directory and connecting a web browser to it.
